{"version":"1.0","type":"rich","title":"123","description":"This sunburst chart displays global CO₂ emissions, with the top-emitting countries grouped by their respective regions. Using D3.js v6, the chart partitions a hierarchical dataset, rendering each segment as an arc whose angle and radius correspond to emission values. The visualization employs `d3.partition` and `d3.arc` for geometry, with regional colors from `d3.schemeCategory10` and country colors from `d3.schemePastel1`. Tooltips reveal exact emission figures, while an interactive legend color-codes both regions and individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c7db78a53504059b9e11293fdd92f36?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
